Surface Technology. "We used to 'home brew' quite a bit,"
Morgan says. This is the type of system most EN shops have
followed for decades.
Less Chance of Human Error
Surface Technology has pushed the One-Plate concept as
a simpler way to manage EN baths, with less chance of
human error.
"The most widely used method to make up and replenish EN
baths is to use three solutions, commonly designated as A, B and
C," says Jijeesh Thottathil, the company's EN solutions manager.
"The A solution contains the metal salt, for example, nickel
sulfate, and may contain other ingredients, and it accounts for
five to six percent of the volume of the plating bath."
He says the B solution contains the reducing agent, such as
sodium hypophosphite, and other functional ingredients like
stabilizers, brighteners, pH buffers, chelators, complexing
agents, accelerators and stabilizers. It accounts for 15 to 20
percent of the volume of the plating bath.
"The balance is typically about 80 percent of the volume of
the plating bath and is made up of water, plus the possibility
of an acid or base to adjust the pH of the EN bath before it is
used for plating," he says.
Classic Plating runs a large EN line with a 1,000-gallon
tank. It also includes a 450-gallon 1001-Q tank, which is
RoHs-compliant.
